Title: Electronic still camera
Inventor: NAKAYAMA MASAAKI
IPC: H04N5/91
Filed: 1986-11-12
Abstract: PURPOSE:To prevent the deterioration of a picture quality due to the generation of a pseudo signal by using the correlation between two adjusent rows and obtaining a luminance signal and chrominance signal. CONSTITUTION:The charge pattern accumulated at an image pickup element 2 is synchronized to a synchronizing signal by an image pickup element driving circuit 15, read successively by scanning, digitized by an A/D converter 3 and thereafter, the pattern is written into a buffer memory 6. After the writing of all screens is completed, two adjusent rows are read from output terminals 6-1 and 6-2 in respective fields. After the signal of two rows is added by an adder 9, processed by a luminance signal processing circuit 10 and goes to a luminance signal Y. On the other hand, the signal of these two rows is respectively processed by chrominance signal processing circuits 11 and 12 and goes to respectively a B-G signal and an R-G signal. These signals are converted to a signal suitable to recording by a recording signal processing circuit 25 and recorded to a recording medium 26 which can be attached and detached freely with a camera main body 22.

IPC: F24F3/147
Filed: 1998-09-24
Abstract: PROBLEM TO BE SOLVED: To provide a ductless ventilating system for a residence capable of ventilating without using the duct relative to a residence except a new building irrespective of a construction method. SOLUTION: Ventilating units 1 are installed respectively in living rooms (living and sitting rooms A, B and C). The amount of supplied air in each ventilating unit 1 is set to be higher than the amount of exhaust air so that each living room has positive pressure. An exhaust type ventilator 17 disposed in a room (lavatory) except the living rooms in a building is always operated so that a part of the air supplied to each living room from each indoor ventilating unit 1 is exhausted outside by the exhaust type ventilator 17 to carry out a ventilation. Thus, a part of air supplied to each living room (indoor air) flows to the lavatory of negative pressure in which the exhaust type ventilator 17 is provided through parts outside the living rooms from each living room of positive pressure and is exhausted outside by the exhaust type ventilator 17.  As a result, a ventilation can be performed outside the living rooms without using a duct to realize a ventilating system for one floor or all the building. Thus, a ventilation can be performed relative to a residence except a new building irrespective of a construction method.

Abstract: PROBLEM TO BE SOLVED: To provide a nonvolatile memory having a boosting line self-aligned wilt a ward line. SOLUTION: In a nonvolatile memory, in which each memory cell transistor has drains 16, channels 18, source 17, floating gates 24 and control gates 30, and the control gates 30 of a large number of memory cell transistors are formed integrally with at least a single word line 28, boosting lines 34 self- aligned with the word line 28 are formed onto the word line 28 via interlayer insulating films 32. First voltage is applied to the word line 28 in a program, and second voltage is applied to the boosting lines 34. Consequently, since voltage on the word line 28 is increased by the capacitive coupling of second voltage on the boosting lines 34, the selected memory cell transistor is programmed. Accordingly, since the memory is used for the word line 28, in which voltage lower than program voltage is selected, a chip area can be reduced, and the memory can be programmed at high speed.
